COMBINED SHAFT-COUPLING AND ANTIRATTLER.

SPECIFICATION formingpart of Letters Patent No. 674,444, dated May 21,1901. 1

Application filed September l8 1900. Serial No. 30,417. (No model.)

To all whmn it may concern/.-

Be it known that I, JOHN J. KOOHER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, (with post-office address at 219 West Fifth street, in saidcity,) have invented certain new and useful Improvements in a CombinedShaft-Coupler and Antirattler, of which the following isa full, clear,and exact description, reference being had to the accompanying drawings,which form a part of this specification.

Myinvention relates to certain new and useful improvements in a combinedshaft-coupling and antirattler; and my invention consists in certainfeatures of novelty hereinafter described and claimed.

Figure I is a top view of my improved de-.

vice. Fig. II is a longitudinal section taken on line II II, Fig. 1.Fig. III is a detail top view of a shaft-iron. Fig. IV is a perspectiveof a coupling, showing the same open. Fig. V is a side elevation of thecoupling, showing it closed.

Referring to the drawings, 1 represents an axle, and 2 a clip forsecuring the coupling to the axle, said clip 2 having the usualscrewthreaded lower end 3, with nuts 4 and clipplate 5 in position.

6 represents the lower jaw of the coupling, which is preferably anintegral part of the clip 2 and is provided at its forward end with alip 7, forming a concave seat 8.

9 represents a shaft-iron, having a yoke 10, the outer ends of said yokebeing connected with a coupling pin 11, surrounded by a washer 12, thewasher being preferably made of some material adapted to yield underpressure.

13 represents a stirrup adapted to straddle the body of the lower jaw,as shown at 14, it being movably secured to the same, so as to move bothup and down and backward and forward. On the upper end of the stirrup 13is a jaw 15, having an overhanging lip 16 with an under concave seat 17.

18 represents a locking-head, somewhat anchor-shaped and having a stem19, one end of said stem being pivoted at '20 to the lower end of thestirrup 13 and having its ends squared, as shown at 21, for receiving awrench 22.

In forming the coupling the shaft-iron 9 is into position, (shown inFigs. II and V,) the convexface 23 of the locking-head 18 engages aconcave face 24 on the under side of the lower jaw 6, the surface ofsaid face gradually approaching the pivot-pin 20, so as to form a clampthat tightens the upper coupling down upon the lower coupling, thustaking up any lost motion or wear between the respective jaws.

25 represents an upwardly-extending heel atthe back of the head18,which,together with the convex face, forms a double bearing for thecoupling-head.

26 represents a shoulder on the stem of the lower jaw 6, said shoulderlimiting the backward movement of the lower end of the stirrup 13. I

I claim as my invention- 1. A combined shaft-coupling and antirattlercomprising a lower jaw having means for securing it to an axle andformed with a lip having a concave seat, a shaft-iron formed with a yokehavingacoupling-pin and washer, a stirrup adapted to straddle the bodyof the lower jaw and formed, at its upperend, with an overhanging liphaving a concave seat, and means for locking the stirrup to the lowerjaw.

2. A combined shaft-coupling and antirattler comprising a lower jawhaving means for securing it to an axle and formed with a lip having aconcave seat, and with a concave surface on its under side, a shaft-ironformed with a yoke having a coupling-pin, a stirrup adapted to straddlethe body of the lower jaw and formed, at its upper end, with anoverhanging lip having a concave seat, and a locking-head having a stempivoted to the lower end of the stirrup and formed with a convex faceand a heel.
